10 C HAPTER 2: I NSTALLATION
V.35 Data Port The V.35 data port is a female, 34-pin connector that provides a V.35 electrical
interface. Pin functions for the interface are listed in Table 2-6.
Only one data port connection can be made at any given time. If the RS-232 port is
in use, the V.35 port unavailable.
FCC rules require that interconnecting cables carrying high speed data be shielded
appropriately in order to minimize radio frequency interference.
Power Connection The PRISM 4101 is powered by a 110 VAC captive power supply. There is no
power switch to turn the unit on or off. When power is applied to the unit, the
front panel indicators illuminate for approximately five seconds as the unit
initializes. The green power LED on the front panel will remain illuminated as
long as the unit receives power.
Per UL 1950 and CSA 950 Clause 1.7.2, if the power supply cord is intended to
serve as a disconnect device, a socket must be installed near the equipment and be
easily accessible.
Power Failure If the indicator does not illuminate, recheck the power connections. For AC
powered units, check the primary AC circuit breaker.
The PRISM 4101 provides non -volatile memory retention of the unit configuration
in case of a power failure. This feature allows the unit to automatically restore
normal service following a power loss.
